It's rarely possible to give any kind of definitive valuation without seeing a watch (pocket or wrist) in person, but it sounds like you have an inexpensive pocket watch that was probably made in the 1960s, less likely made in the 1970s or 1950s. The use of the term 'antimagnetic' on the watch, as opposed to '17 jewels,' suggests that the watch is powered by a 1-3 jewel pin lever movement, rather than a more expensive movement. These movements can keep quite good time, but they are not valued by watch collectors unless the rest of the watch is of compelling interest. In terms of value, your pocket watch has more value as a piece of jewelry than as a vintage timepiece. Most watch collectors would not be particularly interested in your watch. In the United States, I've seen similar watches, in running condition, sell for $5-10 at vintage watch fairs. Around where I live (the Northeast), as a piece of jewelry, your watch may be worth twice that but not more.
